CRAYoN OR LEAD HOLDER.

SPECIFICATION forming part of Letters Patent` o. 267,970, dated November21, 1882.

Application filed October20,1882. (No model.)

To all whom it may concern:

Be it known that I, FRANKLIN W. BROOKS,

a citizen of the United States, residing at New.

York city, New York, have invented `new and useful Improvements inCrayon and Lead Holders, of which the following is a specification.` Myinvention relates to certain new and useful improvements in* crayon orlead holders; and it consists in the peculiarities of construction andoperation hereinafter more fully de-4 scribed and specifically claimed.In theaccompanying drawings, Figure l represents a plan view of a holderembodying my invention; Fig. 2,a central longitudinal section at theline a: m of Fig. 1; Fig. 3, a plan view of the central tube, with thethimblehead portion in section; and Fig. 4.,a crosssection taken at theli'ne y y of Fig. ,2.

Similar letters indicate like parts in the several figures..`

A represents the wooden' barrel, cored axially to receive thecrayon-containing tube B, which is formed at its upper end with a thim-.ble-shaped head, C, having an annular flange,

a, projecting slightly beyond the holder A, and milled or roughened tofacilitate turning the same. This head C having the outwardly-projecting'iiange a enables it to be grasped and operated whether the eraser bepresent or not, and is designed to subserve the special purpose ofoperating in a specified waythe internally-arranged crayon-tube. Thehead or upper end of the case is bored out, of course, to receive thethimble portion G. The tube Bis introduced in the direction indicatedbythe arrow at Fig. l, and is held against retraction by a short screwor pi`n,b, passing through the case or holder A, and projecting slightlyinto a short slotd, Fig. 3, in the upper end of the tube B. Theformation of the slot d is such that it not only prevents retraction ofthe tube, but at the same time permits a limited rotation of the same, ifor the purpose presently explained. This arrangement is necessaryinorder that the tongue e and cam f shall always be held in properrelation to produce the required results. The tube' B vnear its lowerend is formed with a spring-tongue, e, the point of which is turnedinwardly, as seen at Fig. 2, and which may be slightly rough- 4ened. Thepurpose of this tongue e is to grasp and hold the lead when desired,which it is caused to do by a partial rotation ofthe tube B, through themedium of the roughened flange a of the thimble-headC. The central boreof the caseA is enlarged near the point end, as seen at D, andis formedwith a projecting cam, f, adapted to impinge upon the outer surface ofthe spring-tongue, which 'at the point of contact is preferably built upby a round teat, g, Fig. 3. The cam is so constructed with reference 'tothe tongue e that about a quarter-turn of the tube B will be sucient toforce the tongue e inward a sufficient distance to firmly grasp the leadF Within theV tube. A return movement of the tube B will obviouslyrelease the tongue e, and its spring capacity will cause it to move awayfrom the lead and'permit the latter to slide freely within the tube. Any

suitable spring mechanism may be connected to the tube B toautomatically rotate it to the position necessary to force the tongue einwardly, so that after it has been positively released to permit thelead to be projected a suitable distance beyond the point of the case,or entirely concealed within the same, the tongue willbe automaticallyoperated to prevent further movement of the lead. This spring foractuating the tube B, as just described, is notan absolute necessity, asit may be operated entirely by hand. The tongue c is formed in one sideofthe lead-tube, a-suitable distance from or above the point or tip, andso that the latter is left unbroken to give a complete circumferentialsupport to the projecting lead; vand the tongue e, being arranged in oneside of the tube, as described, also operates in such manner as tocompress the lead against the opposite continuous surface of the tube,thus getting a longbearing against the lead, and avoiding the tendencyexisting in the ordinary split or double-jawed tubes of pinchingorbiting the lead, or weakening it at the point where it should have thegreatest tenacity.

Eis a lead-Sharpener and eraser, adapted to be removably located withinthe thimblehead G, so that the sharpener may be used to point the leadby entirely removing same from its seat, or the eraser may be concealedand IOO protected, as shown. I do not, however, lay

claim to this construction in this case, but refer for a more particulardescription of the same to another case tiled simultaneously.

In introducing the tube B, it will be readily observed the spring-tonguec, being forced inward, easily passes through the more contractedportion of the central bore of the case A, and when reaching the portionD it naturally springs outward. The tongue may vbe integral with thetube, or made separately and secured thereto by a rivet or otherwise.

What I claim as new, and desire to secure by Letters Patent, is

1. In a lead or crayon holder, the tube B, adapted to be partiallyrotated and havingin one side only a spring-tongue, e, above the tip orend of the tube, in combination with the case A and cam f formedtherein, whereby the lead is held at a point above or inside 2o the tip,substantially as described. 2. The combination and arrangement, with thecase A, having` hollow head, and camf, of
